We import cali ourselves, top-tier grown in and around [retracted] . It just depends on who you shop with, we believe marketing as a difficult topic since there may also be import products sold, if you have had issues regarding import or cali flower on LB you should start a topic about the vendor issues. Caliweed is something sought after, in general it is just weed grown with higher standards. If the weed doesn't check the boxes of smell, taste, high aswell as appearance it should not be cali. Obviously if vendors sell from USA it might be hard to distinguish if something really is from Cali, in the end only the vendors truly can have information about the destination of production.
Also from someone who is really connected around the globe:
Many calipacks come without labels because they are sold without taxes, essentially its recreational weed sold in a black market. This mostly happens to overproduction, or production that did not check all boxes for rc market i.e. dispensaries. Often sold by bigger famous corps but also small black market only corps aswell, those huge amounts of packaged flower aswell as loose flower are sold to big big plugs.
Back to the Calibag topic:
In general Cali should only be bought from truly credible vendors.
Also labeled Cali bags should be controlled because the ones with labels qr codes are the most faked, always check authenticity via scanning qr codes if available. A red flag is if there are no sticker labels on bags, (doesn't have to be fake cali, tho its rare)
